RESUMEN
Objective To explore the value of MSCTU in ureterovesical junction diseases.Methods MSCTU data in 41 patients with different diseases in ureterovesical junction were retrospectively analyzed.All patients underwent plain and triphase contrast en-hanced CT scans.The primary imaging data were transmitted to a worksation to get the maximum intensity projection (MIP),vol-ume rendering (VR),multiplanar reconstruction (MPR)and curve plannar reconstruction (CPR)images.Results (1)CT showed congenital abnormality in 7 patients including ectopic ureteral orifice in 1,megaloureter in 1,duplication of the urter in 4 and uret-erocele in 2.(2)Urinary stone in 25 with bladder filling defect in 1 1.(3)Tumor in 9 including polyp in 1,urothelial carcinoma in 6 and prostate cancer in 2.MSCTU clearly showed the location,shape,size of the ureterovesical junction diseases and the relationship with surrounding structures.Conclusion MSCTU plays an important role in diagnosis of ureterovesical junction diseases with an ac-curate rate of 97.5%(40/41).
